Measurements of the production of jets of particles in association with a Z boson in pp collisions at √s=7 TeV are presented, using data corresponding to an integrated luminosity of 4.6 fb-1 collected by the ATLAS experiment at the Large Hadron Collider. Inclusive and dierential jet cross sections in Z events, with Z decaying into electron or muon pairs, are measured for jets with transverse momentum pT > 30 GeV and rapidity jyj < 4.4. The results are compared to next-to-leading-order perturbative QCD calculations, and to predictions from dierent Monte Carlo generators based on leading-order and next-to-leading-order matrix elements supplemented by parton showers.

Abstract
Measurements of the production of jets of particles in association with a Z boson in pp collisions at √s=7 TeV are presented, using data corresponding to an integrated luminosity of 4.6 fb-1 collected by the ATLAS experiment at the Large Hadron Collider. Inclusive and dierential jet cross sections in Z events, with Z decaying into electron or muon pairs, are measured for jets with transverse momentum pT > 30 GeV and rapidity jyj < 4.4. The results are compared to next-to-leading-order perturbative QCD calculations, and to predictions from dierent Monte Carlo generators based on leading-order and next-to-leading-order matrix elements supplemented by parton showers.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
